# Prologue (Jomaku)

Prologue (Jomaku) (プロローグ〈序幕〉, Purorōgu (Jomaku), Prologue (Introduction)) is the debut studio album by Japanese entertainer Akina Nakamori. It was released on July 1, 1982, by Warner Pioneer under the Reprise Records label. The album includes the debut single "Slow Motion". It was recorded in the Los Angeles music studio, three months before Nakamori's debut.

## Background

Prologue (Jomaku) is the first studio album released in 1982, two months after the release of her debut single "Slow Motion".
The early production of the album began in February and was finished within 5 days. There were five candidate songs to be chosen as a debut single: Slow Motion, Ginga Densetsu, Anata no Portrait, T-Shirt Sunset and Jōken Hansha. From among them, Slow Motion was chosen. During that time, most of the idols had debuted with an uptempo single, while the production staff wanted to make a difference in Nakamori's case and made a debut with a slow ballad.
The music production team consisted of Motoki Funayama, siblings Etsuko and Takao Kisugi, Mayumi Shinozuka, Tsuzuru Nakasato, Yuji Ohno and Shizuka Ijūin.
